Thank you!!! ​

Answer 1

construct bg perpeento de and also bg=de

in triangle aed and bgc,

ad=bc

angle DEA = angle BGC

bg = de

by sas rule, they are congruent

therefore, bg=ad ( by cpct)

also constructed bg=de

so de= bg = ad

hence, AD = 6cm

Answer 2

Answer:

we know that,

area of parallelogram = base × height

in case 1 DE is the base and AB is the height

= DE × AB

= 6 × 10

= 60 cm²

Now, in 2nd case,

AD is the base and BF is the height

base × height = area

=> AD × BF = area

=> AD × 8 = 60cm²

=> AD = 60/8

=> AD = 7.5cm

I hope this answer helps you.
